VIOLET GERTRUDE GRENALL, OF NEW YORK, N. Y.

HAIR-GURLIING- DEVICE.

Specification of Letters Patent.

Patented Mar. 22. 1921.

Application filed September 5, 1919. Serial No. 321,773.

To aZZ whom it may concern:

Be it known that I, VIOLET; Gnn'rnunn GRENALL, a citizen of the United States, residin at New York, county of New York, and btate of New York, have invented certain new and useful Improvements in Hair- Curling Devices, of which the following is a specification.

This invention relates to improvements in hair curling instruments, especially to improvements in the so-called Marcel wavers and it is the primary object of the invention to provide an instrument of this class which will form lasting waves in the hair.

Another object of the invention is to provide an electrically operated Marcel wafier, which can be conveniently handled to quickly produce waves in the hair.

A further object of the invention is to provide a hair curling instrument which may be readily heated by electricity or gas, or by an alcohol torch in a convenient manner.

Other features of novelty will be more fully described in connection with the accompanying drawing and will be more particularly pointed out in and by the appended claims.

The drawing herewith submitted represents a hair curling instrument in a-form serving as an example for execution and as follows:

Figure 1 is a side view of the instrument constructed according to the present invention, partly in section.

Fig. 2 shows a perspective view of one of the tubes for the reception of the heating rods, partly in section.

Fig. 3 is a perspective detail view of the tube holder, and

Fig. 4 is a perspective detail view of one of the heating rods.

Referring particularly to the drawings,

2 the instrument comprises a pair of tubes 11,

12 to be heated by electricity, gas or any other suitable source of heat.

The front ends of these tubes are extended into a housing or casing'13 in which they are held in parallel alinement by aspring 14 engaging their ends and tending to press their triangular extensions 15 into engagement with the teeth 16 of a rack bar 17 within said casing.

Into the opposite ends of the tubes 11 and 12 heating rods 18 and 18. are extended provided with heads 19 and 19'. These heads are normally located within a housing or casing 20 and held therein between a rack 21 and angular sprlngs 22, secured to the inner wall of the casing 20; for the purpose insulating tubing 27", through the socket,

and their inner ends are secured to pole screws 28 and 28 to which also the ends of contact springs 29 and 29 are secured, making electrical contact with the springs 22 and by their intermediary, also with the heads 19 and 19' of the heating rods 18 and 18'.

It will be clear that the'housings 13 and 20 must be made of heat insulating material so as to allow a convenient handllng of the lnstrument. A

The heating rods 18 are held within their respective tubes by means of engagement of their peripheral notches 30 by a tongue or the like 31 bent out of the material of the tubes 11 and 12.

In operation, the hair to be curled is placed between the two tubes and is twisted around them in such a manner that it will represent substantially the figure 8 in crosssectlon.

After the introduction of the heating rod and closing of the circuit, the heat transmitted from said rod and tubes will curl the hair and form waves in the same, thereafter the rods are removed from the tubes and the hair can be slipped off the tubes.

hat I claim is l. A hair curler of the character described, comprising a pain of tubes, inner lips and triangular noses in said tubes, heating rods having a peripheral groove adapted to be engaged by said lips of the tubes, a casing for the ends of said tubes, a rack in said casing, and a spring for pressing said triangular noses into engagement with the teeth of said rack, means for transferring heat to said rods, and means for detachably holding the ends of said rods in engagement, with said heat transferring means,

2. A Marcel waver of the character described, comprising a pair of hair holding tubes, means for holding said tubes in parallel alinement, heating rods adapted to be engaged with and held within said tubes, a casing, toothed heads on said r0 s, a rack in sa1d casing adapted to engage the teeth of said heads, means for holding said teeth in engagement, and electrical conductors for transferring the heat of a source to said heads, rods and tubes, substantially as described and for the purpose set forth.

3. A hair curler of the character described, comprising a pair of hair holding tubes, means for holding both tubes in parallel alinement, heating means in said tubes, means for holding said rods in said tubes, a

casing, a rack bar in said casing, toothed heads on said rods adapted to engage said rack bar, angular springs within said casing for pressing said heads in-engagement with said rack, a socket adapted to removably engagesaid casing, conductor wires adapted to be secured to a source of electricity, pole screws in said casing to which the ends of said wires are secured,and contact springs connecting said pole screws'and .said angular springs for constituting a circuit closing means for electrically heating said rods and tubes substantially as described. In testimony whereof Ihave affixed my signature. 7 r
